本文根据鸡面山隧道工程的水文地质勘察资料,分析评价了其地质构造、地下水的发育、地表水的发育、地下水及地表水的补给等水文地质特征,并采用径流模数法预测了隧道的正常涌水量和最大涌水量。预测结果表明,隧道的正常涌水量和最大涌水量分别为860m3/d和1283m3/d,由此确定了隧道全线属贫富水区段、构造带段属弱富水区段,进而提出了隧道的施工建议,供同行参考。
Based on the hydrogeological survey data of Jimianshan tunnel project, this paper analyzes and evaluates the hydrogeological features of the geological structure, the development of groundwater, the development of surface water, the recharge of groundwater and surface water. The runoff modulus Normal water inflow and maximum water inflow. The prediction results show that the normal water inflow and the maximum water inflow of the tunnel are 860m3 / d and 1283m3 / d, respectively, which confirms that the whole tunnel belongs to the poor and rich water section and the structural belt belongs to the weak and rich water section, and then proposes the tunnel Construction recommendations for peer reference.
